California City, California Apr 21, 2022 (Issuewire.com) - What is the difference between laser projection and ordinary projection? As we all know, the concept of laser projection has not been proposed for a long time, but it is developing rapidly. Laser projection offers a revolutionary development possibility for projectors. In addition to the high price, other aspects of performance are very outstanding.
First of all, eye protection. The laser light source is less harmful to the human eye.
In fact, human eyes have long been accustomed to the environment of sunlight reflection, and the laser display has a higher color gamut coverage and is closer to the colors that can be recognized by the human eye. The ultraviolet light in the light source of the laser projection is absorbed and filtered after being reflected by the optical screen, and the blue light with the blue light wavelength below 450nm is absorbed.
Laser light source is the use of the photoelectric effect so that the excited state particles under the action of exciting radiation light source. Smart micro projectors are also gradually adopting this light source, such as the Dangbei Mars Pro laser projector and Epson Home Cinema LS11000.
Laser light source life can reach more than 25000 hours. At 10 hours per day, it has a lifespan of up to 8 years, and at least 10 years at 8 hours per day.
Also, the claim that light sources slowly diminish in brightness over time is true for the ultra high-pressure mercury lamps used in projectors. Theoretically, due to the longer lifespan, laser light sources can maintain their brightness for a very long time without fading.
Nowadays, more and more projectors adopt 4K resolution. 4K resolution ensures the projection image with high definition. The tiniest details can be shown perfectly on a large screen.
The projector with the laser source and 4K resolution will improve a lot of the viewing experience. But the cost of 4K laser projectors is relatively higher than ordinary projectors. The prices of the Dangbei Mars Pro laser projector and Epson Home Cinema LS11000 mentioned before are ＄1799 and ＄3999.
Nowadays, with projectors brands and manufacturers launching more and more laser projectors, they are also trying to reduce the cost of the laser source to make it more cost-effective and accessible to projector users.
